Application filed February 25, 1893. Serial No. 463.768- (No model.)

To all whom it may concern.-

Be it known that I, RALPH LATHROP PAD- DOOK, of the city and county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Automatic Operators for Drawbridge-Gates, of which the following, taken in connection with the accompanying drawings, is a specification.

The object of this invention is to open and close the gate connected with a drawbridge without the services of an attendant.

In the drawings, Figure 1 is a perspective View,showinga gate on the land, at the'brink of the draw, and the devices engaged which operate the gate when the bridge is moving to open or close the draw. These devices consist of a finger or bar secured to the bridge and a pivoted latch which I term the operator attached to the gate, the said finger being the instrument bywhich the latch is actuated and the gate opened and closed. Fig.

in the operator, and carries the gate back from whence it started. By this means thegate is securely locked.

I claim as my invention-- 1. In a draw-bridge gate, the finger A secured to the bridge, in combination with the latch B pivoted on the free end of the gate, the connecting bar'C and the wheels W W, substantially as set forth.

2. The latch B pivoted on the gate, the connecting bar C jointed to the latch and to the cross-bar c, and the supporting wheelsW W in combination with the finger A on the bridge, and the track T and offset '1" and T substantially as set forth.
